Computational Module for the Buckling and Post-Buckling Behavior of a CylindricalShell with a Two-Mode Imperfection

摘要

The implementation of anisotropic buckling equations into a computer program isdescribed in this report. The well known Donnell type (shallow shell) equations are used for the analysis. The imperfections are given in a two-mode shape, containing one axisymmetric and one asymmetric mode. The asymmetric mode has a skewedness parameter included in order to account for a skewed buckling pattern.
